TECHNICAL FIELD

The subject matter disclosed herein relates generally to gaming machines and more particularly, to an apparatus and method for allowing players to play a keno-type game having non-player selectable symbols on gaming machines.

BACKGROUND OF THE INVENTION

At least some known gaming machines display keno games that include a plurality of numbers that are displayed on a keno board and are selectable by the player. During play of known keno games, the player selects one or more of the numbers displayed on the keno board and inputs the selections to the gaming machine. The gaming machine conducts a draw wherein the gaming machine randomly selects a predefined number of balls, each representing a corresponding number displayed on the keno board. After the gaming machine has completed the draw, the gaming machine compares the numbers selected during the draw to the numbers selected by the player and provides the player an award based on the number of matches that occur between the player selected numbers and the machine selected numbers.

Over time, during game play, the player may become frustrated because the chances of receiving an award are based only of the number of matches made between the player selected numbers and the machine selected numbers. Accordingly, new features are necessary to appeal to player interest and enhance excitement in order to entice longer play and increased profitability. The present invention is directed to satisfying these needs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the drawings and in operation, the present invention overcomes at least some of the disadvantages of known gaming machines by providing a gaming machine that allows the player to play a keno-type game that provides the player an enhanced award if a triggering condition occurs in the outcome of the keno-type game. More specifically, the gaming machine allows a player to play a keno-type game that includes a set of player selectable game symbols and a non-player selectable game symbol, and modifies an outcome of the game if the gaming machine selects the non-player selectable game symbol during the game. In addition, the gaming machine allows a player to select a first collection of game symbols from the set of player selectable game symbols, and randomly draws a second collection of game symbols from the set of player selectable game symbols and the non-player selectable game symbol. The gaming machine determines if a game symbol selected in the second collection matches the non-player selectable game symbol and responsively modifies the game outcome if the non-player selectable game symbol is selected. For example, if the non-player selectable game symbol is drawn in the second collection, the gaming machine may provide a bonus multiplier, free bonus rounds, additional player selections, additional draws, and/or stop the draw. By providing a gaming machine that displays a keno-type game that has a non-player selectable game symbol and that provides and/or modifies an award if the non-player selectable game symbol is drawn, the player's expectation for achieving a win is increased and the enjoyment of the game is improved. Thus, the amount of time that the game is played by patrons of a gaming establishment is thereby increased.

In general, the gaming machine 10 allows a player to initiate a gaming session to play a keno-type game via the gaming machine 10. The gaming machine 10 displays a game including a plurality of game symbols including a plurality of player selectable symbols and at least one non-player selectable symbol, accepts a wager on the game, and allows the player to select a plurality of game symbols from a set of player selectable symbols. The gaming machine 10 conducts a draw and randomly selects game symbols from the plurality of game symbols including the set of player selectable game symbols and the non-player selectable game symbol. The gaming machine 10 also determines if a triggering condition occurs including the selection of the non-player selectable gaming symbol during the draw, and generates an outcome of the game based on the player selected symbols, the symbols selected during the draw, and the triggering condition. The gaming machine 10 also provides an award to the player that is determined as a function of the number of games symbols selected by the player that match the game symbols selected during the draw and the occurrence of the triggering condition.

During game play, if the triggering condition occurs, the gaming machine 10 modifies the outcome of the game. For example, the gaming machine 10 may provide a bonus multiplier to the player and provide an enhanced award to the player equal to the award and the bonus multiplier. In addition, the gaming machine 10 may increase the number of symbols selected during the draw. Moreover, the gaming machine 10 may award the player additional free games and/or award the player additional games and an award bonus multiplier. In one embodiment, the gaming machine 10 also may stop the draw after the triggering condition occurs. Because the gaming machine 10 modifies the outcome of the game if the non-player selectable game symbol is selected during the draw, the player's anticipation of an additional award is increased, thus increasing the period of time the gaming machine 10 is played by the player.

A selected embodiment of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following description of the embodiment of the present invention is provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

The display module 58 controls the display device 12 to display various images on screens preferably by using computer graphics and image data stored in the memory device 52. More specifically, the display module 58 controls the game symbols displayed in a keno-type game screen displayed on the display device 12 by using computer graphics and the image data.

The player selection module 60 receives a player selection input from the input device 14 and selects game symbols based on the player's selection. The random-number generator (RNG) 56 generates and outputs random numbers to the processor 48 preferably at the start of each round of game. The draw selection module 62 generally uses the random numbers to select one or more game symbols from the plurality of game symbols. In addition, the processor 48 may use random numbers generated by the RNG 56 to determine if a triggering condition has occurred in the outcome of the game, and to determine whether or not to provide an award to a player. For example, if the game is a keno-type game, the draw selection module 62 uses the RNG 56 to randomly select a plurality of game symbols during a symbol draw. In another embodiment, the player selection module 60 may use the random numbers to select the player selected game symbols. For example, a player may select a “quick-pick” operation via the user input device 14, wherein the player selection module 60 uses the random numbers to select one or more game symbols for use as the player selected game symbols.

The processor 48 compares the game symbols selected by the draw selection module 62 to the player selected game symbols selected by the player selection module 60 to determine a number of player selected symbols matching the randomly selected game symbols. The processor 48 also compares the determined symbol matches with winning combinations stored in the winning combination table to determine if the symbol matches include a winning outcome that is associated with a type of award. In addition, the processor 48 determines if a triggering condition occurred in the game and modifies the game outcome based on the triggering condition.

FIG. 3 is a graphical display of the keno-type game 64 that is displayed by the gaming machine 10 shown in FIG. 1. FIG. 4 is another graphical display of the keno-type game 64 that may be played with the gaming machine 10. In the illustrated embodiment, the gaming controller 16 is configured to display the game 64 on the display device 12. In one embodiment, the game 64 is a video keno game. However, it should be noted that the game 64 may be any type of game upon which a player could make a wager including, but not limited to a slot game, a blackjack game, a video poker game, or any type of game that enables the gaming machine 10 to function as described herein.

In general, during play of the game 64, the gaming controller 16 displays the game including a plurality game symbols 66. The plurality of game symbols 66 include a set 68 of player selectable game symbols 70 and at least one non-player selectable game symbol 72. The set 68 of player selectable game symbols 70 includes game symbols that are selectable by the player for use during the game 64. More specifically, the player selectable game symbols 70 include game symbols 66 that may be selected by the player via the user input device 14 and are used by the gaming controller 16 for determining an outcome of the game 64. The non-player selectable game symbols 72 include game symbols 66 that are not selectable by the player. Moreover, the non-player selectable game symbols 72 are only available for selection by the draw selection module 62 for use in determining an outcome of the game 64.

In the illustrated embodiment, the plurality of game symbols 66 are displayed in a grid 74 having a plurality of symbol positions 76 arranged along a plurality of rows 78 and a plurality of columns 80. Each symbol position 76 displays a corresponding game symbol 66. In the illustrated embodiment, the gaming controller 16 displays the game 64 including a total of 81 symbol positions 76 displayed within the grid 74 arranged in 9 rows 78 and 9 columns 80 in a “9×9” arrangement. Alternatively, any number of symbol positions 76 may be displayed in any suitable grid arrangement including, for example, 80 symbol positions 76 displayed in a 8×10 arrangement, 40 symbol positions 76 displayed in a 5×8 arrangement, 72 symbol positions 76 arranged in a 7×7 arrangement, and/or any suitable number of symbol positions 76 displayed in any suitable row 78 and column 80 combination to enable the gaming controller 16 to function as described herein. Moreover, the gaming controller 16 may display the game 64 including a plurality of grids 74 including a first grid 77 and a second grid 79 (shown FIG. 4).

Each keno game is generally played in a conventional manner. The player makes a wager, which may be based on a predetermined denomination and a selected number of game symbols to be selected by the player and/or a selected number of game symbols to be drawn by the gaming controller 16, selects one or more game symbols from the plurality of game symbols, and initiates a symbol draw operation. During the symbol draw operation, the gaming controller 16 randomly selects one or more game symbols 66 and compares the player selected game symbols with the drawn game symbols. The gaming controller 16 displays an outcome of the game 64 including a number of matched symbols between the player selected symbols and the drawn symbols and provides an award to the player based on the number of matched symbols, the wager, and a predetermined paytable. Moreover, the gaming controller 16 may determine a type of game symbol that is matched between the player selected symbols and the drawn symbols and award a payout if the matched symbol types are associated with a predefined symbol type. Many variations to the above described general play of a keno game fall within the scope of the present invention. Such keno games are well-known in the art, and are therefore not further discussed.

In the illustrated embodiment, the gaming machine 10 receives a signal from the user input device 14 that is indicative of a player's selection to initiate a gaming session including a wager amount and a selection of one or more game symbols 66. More specifically, the gaming controller 16 displays the game 64 including the set 68 of player selectable game symbols 70 and the non-player selectable game symbol 72. In one embodiment, shown in FIG. 3, the game 64 is displayed having the plurality of symbol positions 76 arranged in the grid 74 having a central symbol position 82. The non-player selectable game symbol 72 is displayed in the central symbol position 82 with the player selectable game symbols 70 displayed in the symbol positions 76 surrounding the non-player selectable game symbol 72. Alternatively, the non-player selectable game symbol 72 may be displayed in any symbol position 76 within the grid 74 and/or displayed in a symbol position 76 located adjacent to the grid 74 (shown in FIG. 4). In one embodiment, the non-player selectable game symbol 72 is not displayed with the game outcome 64 such that the non-player selectable game symbol 72 is not visible by the player during the game 64.

In the illustrated embodiment, each player selectable game symbol 70 is displayed with a corresponding reference number. For example, in the illustrated embodiment, the set 68 of player selectable game symbols 70 include symbols 1 through 80. In addition, the non-player selectable game symbol 72 may be displayed with a reference numeral and/or be displayed with a symbol image 84, e.g. a “star” symbol shown in FIG. 3. In another embodiment, each player selectable game symbol 70 is displayed with a corresponding symbol image 84 as shown in FIG. 4.

In the illustrated embodiment, the gaming controller 16 operates in a player selection mode, a draw selection mode, and a match determination mode. During game play, the controller accepts a wager from the player to initiate play of a first round of the game 64. In the player selection mode, the gaming controller 16 selects a first collection 86 of game symbols 66 based on a player selection input received from the input device 14. More specifically, the player selection module 60 selects one or more player selectable game symbols 70 based on the player selection input received from the input device 14. Alternatively, the player selection module 60 may use random numbers from the RNG 56 to randomly select one or more player selectable game symbols 70 included in the first collection 86. The first collection 86 is selected from the set 68 of player selectable game symbols 70 and includes one or more player selectable game symbols 70 that are selected by the player selection module 60. The gaming controller 16 displays the first collection 86 on the game screen 26 by displaying each selected game symbol 66 with a first marking 88 (displayed as a “slash” mark in FIGS. 3 and 4) and/or modifying the symbol image 84 associated with the player selected symbol to indicate the selection to the player.

In the draw selection mode, the gaming controller 16 randomly selects a second collection 90 of game symbols 66 during a symbol draw. The second collection 90 is selected from the plurality of game symbols 66 including the set 68 of player selectable game symbols 70 and the non-player selectable game symbol 72. More specifically, the draw selection module 62 uses random numbers from the RNG 56 to select one or more game symbols 66 included in the second collection 90. The gaming controller 16 displays the second collection 90 on the game screen 26 by displaying each selected game symbol 66 with a second marking 92 (displayed as a “circle” mark in FIGS. 3 and 4) and/or modifying the symbol image 84 associated with the randomly selected second collection 90 to indicate each game symbol 66 selected during the draw. In the illustrated embodiment, the gaming controller 16 determines a number of game symbols 66 to be selected for the second collection 90 during the symbol draw. In one embodiment, the gaming controller 16 determines the number of selections made during the draw as a function of a wager made by the player, a player selection input, and/or a number of game symbols 66 selected by the player during the player selection mode. Alternatively, the gaming controller 16 may select a predefined number of selections for the second collection 90. In addition, the gaming controller 16 may randomly select a number of selections to be made for the second collection 90 based on the player's wager, the symbols selected in the first collection 86, symbol weights, paytables, and/or winning combination tables.

In the illustrated embodiment, the non-player selectable game symbol 72 may be selected only once during the symbol draw. For example, if the gaming controller 16 determines that 5 game symbols 66 will be selected during the draw and the draw selection module 62 selects the non-player selectable game symbol 72 as the 1^(st) drawn symbol, the non-player selectable game symbol 72 is not available for the remainder of the symbol selections. Alternatively, the non-player selectable game symbol 72 may be selected more than once during the symbol draw such that non-player selectable game symbol 72 is available to be selected for each selection made by the draw selection module 62 during the symbol draw. Moreover, in one embodiment, the non-player selectable game symbol 72 may only be available for a predefined number of selections, for example, if the draw selection module 62 has selected the non-player selectable game symbol 72 twice during the symbol draw, the non-player selectable game symbol 72 is not available to be selected for the remainder of the symbol selections made in the symbol draw. In addition, if more than one non-player selectable game symbol 72 is displayed in the game 64 (as shown in FIG. 4), each non-player selectable game symbol 72 may be selected only once during the symbol draw, and/or at least one non-player selectable game symbol 72 may be selected more than once during the symbol draw.

In the determination mode, the gaming controller 16 determines if a triggering condition occurs and generates an outcome of the game 64 based on the selected first collection 86, the selected second collection 90, and the occurrence of the triggering condition. The gaming controller 16 also determines a number of randomly selected game symbols 66 included in the second collection 90 matching the game symbols 66 included in the first collection 86. In addition, the gaming controller 16 provides an award to the player that is determined as a function of the outcome based at least in part on the determined number of game symbols 66 from the second collection 90 matching the game symbols 66 in the first collection 86. In general, the term “award” may be a payout, in terms of credits or money. Thus, the gaming controller 16 may award a regular payout in response to the outcome of the game 64. However, it should be noted that the term award may also refer to other types of awards, including, prizes, e.g., meals, show tickets, etc. . . . , as well as in-game award, such as free games, bonus symbols, and/or special game modes.

In the illustrated embodiment, the gaming controller 16 provides an enhanced award to the player if the triggering condition occurs. In one embodiment, the enhanced award includes an award multiplier that increases an amount of the award received by the player such that the enhanced award is equal to an award based on the number of game symbol matches multiplied by the award multiplier. In another embodiment, the enhanced award may be one or more additional rounds of the game 64 and/or one or more additional games. During each additional game round, the gaming controller 16 may conduct an additional symbol draw and select an additional number of game symbols 66, and provide the player an award based on the number of matches between the additional drawn game symbols 66 and the game symbols 66 previously selected by the player. In addition, in one embodiment, the gaming controller 16 may allow the player to select the game symbols 66 for each new round. Moreover, in one embodiment, the player may select a new collection of game symbols 66 for each additional game. In addition, the gaming controller 16 may award the player an enhanced award during each subsequent game round and/or game in which the trigging condition occurs.

In the illustrated embodiment, the triggering condition occurs when at least one of the randomly selected game symbols 66 in the second collection 90 matches the non-player selectable game symbol 72. During play of the game 64, the gaming controller 16 determines if any of game symbols 66 selected in the second collection 90 matches the non-player selectable game symbol 72 and determines the triggering condition to have occurred if a selected game symbol 66 matches the non-player selectable game symbol 72. In one embodiment, the non-player selectable game symbol 72 may be selected during each selection of the second collection 90. The gaming controller 16 determines a number of game symbols 66 in the second collection 90 matching the non-player selectable game symbol 72 and provides an enhanced award to the player based on the determiner number of non-player selectable game symbol matches. In addition, in one embodiment, the gaming controller 16 provides an enhanced award that includes an award multiplier that is indicative of the number of non-player selectable game symbol matches. For example, the gaming controller 16 may determine the second collection 90 includes 5 non-player selectable game symbol matches, and provides the player an enhanced award equal to a 5× multiplier factor, and awards the player a total award equal to the award for matches between the first and second collections 86 and 90 multiplied by the 5× multiplier factor. Moreover, in one embodiment, the gaming controller 16 may provide an enhanced award that includes a special game mode, a number of additional game rounds, and/or additional games that is equal to the number of non-player selectable game symbol matches.

In one embodiment, the gaming controller 16 may award the player a plurality of predefined enhanced awards, wherein each predefined enhanced award is associated with a corresponding number of non-player selectable game symbol matches. For example, in one embodiment, the gaming controller 16 determines a number of non-player selectable game symbol matches included in the second collection 90. The gaming controller 16 also determines the predefined enhanced award associated with the determined number of matches and provides the enhanced award to the player. In one embodiment, each predefined enhanced award may have an increasing value corresponding to an increasing number of matches. For example, the gaming controller 16 may award a 2× award multiplier for 2 non-player selectable game symbol matches, award the 2× award multiplier and a bonus game for 3 non-player selectable game symbol matches, and award a 4× award multiplier for more than 4 non-player selectable game symbol matches. Moreover, the gaming controller 16 may award any suitable combination of enhanced awards corresponding with any suitable number of predefined non-player selectable game symbol matches. In addition, the number of non-player selectable matches may be determined for each game round, or may be accumulated over several game rounds such that the controller provides an enhanced award corresponding to the cumulative number of non-player selectable game symbol matches made during a predefined number of game rounds.

In one embodiment, during the draw selection mode, the gaming controller 16 determines a number of game symbols 66 to be selected for the second collection 90 and randomly selects a game symbol 66 for each of the number of game symbol selections. The gaming controller 16 also determines whether the triggering condition occurs in each selection before making a subsequent selection, and stops the symbol draw selection if the triggering condition occurs. For example, in one embodiment, the gaming controller 16 determines that 5 selections will be made during the symbol draw and, for each selection, determines if the triggering condition occurs. If the triggering condition occurs after the 3^(rd) selection is made, the gaming controller 16 stops the symbol draw and does not select the 4^(th) and 5^(th) symbol selections. Moreover, if the gaming controller 16 determines that the 3^(rd) game symbol selected matches the non-player selectable game symbol 72, the gaming controller 16 stops the draw selection and determines the award based on the drawn game symbols 66.

In one embodiment, the gaming controller 16 may increase the number of game symbols 66 included in the symbol draw of the second collection 90 if the triggering condition occurs during the symbol draw. For example, in one embodiment, the gaming controller 16 may determine a first number of game symbols 66 to be selected for the second collection 90, randomly select a game symbol 66 for each of the first number of selections, and, for each selection, determine if the triggering condition has occurred. Upon determining that the triggering condition has occurred, the gaming controller 16 may determine a second number of game symbols 66 to be selected for the second collection 90 such that a total number of selections made for the second collection 90 is equal to the first number of selections and the second number of selections. Alternatively, the gaming controller 16 may award the player a predefined number of additional player selections for the first collection 86 if the triggering condition occurs in any selection made during the symbol draw. For example, if the triggering condition occurs during the symbol draw, the gaming controller 16 may suspend the draw and award the player additional symbol selections for the first collection 86 such that the total number of game symbols 66 in the first collection 86 is increased. Once the player has made the additional selections, the gaming controller 16 may continue the symbol draw and provide an award as a function of the matches between the total number of game symbols 66 in the first collection 86 and the game symbols 66 in the second collection 90.

In one embodiment, the gaming controller 16 may remove a predefined number of game symbols 66 that may be selected from the symbol draw to increase a probability of a first collection symbol 86 to be selected by the draw selection module 62 during the symbol draw. For example, upon determining the triggering condition has occurred, the gaming controller 16 determines the game symbols 66 that are not included in the player selected first collection 86 and removes one or more of the non-selected symbols from the game symbols 66 available for the symbol draw. By removing the non-selected symbols, the probability of a first collection symbol 86 being selected in the symbol draw is increased. Moreover, in one embodiment, upon determining the triggering condition has occurred, the gaming controller 16 may convert one or more game symbols 66 to a bonus symbol, wherein the gaming controller 16 provides an enhanced award to the player if the bonus symbol is included in the second collection 90 during the symbol draw.

An exemplary technical effect of the methods, systems, and computers described herein includes at least one of (a) allowing a player to make a wager and responsively displaying, on a display device, a first round of the keno-type game including a plurality of game symbols, the plurality of game symbols including a set of player selectable game symbols and a non-player selectable game symbol; (b) selecting a first collection of game symbols based on a player selection input received from an input device, the first collection being selected from the set of player selectable game symbols; (c) randomly selecting a second collection of game symbols, the second collection of game symbols being selected from the set of player selectable game symbols and the non-player selectable game symbol; (d) determining if a triggering condition occurs, the triggering condition being defined as at least one of the randomly selected game symbols in the second collection matching the non-player selectable game symbol; (e) generating an outcome of the first round game based on the selected first collection and the selected second collection and the occurrence of the triggering condition; and (f) providing a first award determined as a function of the outcome based at least in part on a number of randomly selected game symbols in the second collection matching the player selected game symbols in the first collection.

The above-described systems and methods overcome at least some disadvantages of known gaming machines by providing a gaming machine that allows a player to player a keno-type game that includes a set of player selectable game symbols and a non-player selectable game symbol, and modifies an outcome of the game if the gaming machine selects the non-player selectable game symbol during the game. In addition, the gaming machine allows a player to select a first collection of game symbols from the set of player selectable game symbols, and randomly draws a second collection of game symbols from the set of player selectable game symbols and the non-player selectable game symbol. The gaming machine determines if a game symbol selected in the second collection matches the non-player selectable game symbol and responsively modifies the game outcome if the non-player selectable game symbol is selected. For example, if the non-player selectable game symbol is drawn in the second collection, the gaming machine may provide a bonus multiplier, free bonus rounds, additional player selections, additional draws, and/or stop the draw. By providing a gaming machine that allows the player to play a keno-type game that provides enhanced awards if a triggering condition occurs during the game, the player's expectation for achieving a win is increased and the enjoyment of the game is improved. Thus, the amount of time that the game is played by patrons of a gaming establishment is thereby increased.
